WCAG 2.2 AA.
Web Content Accessibility Guidelines
WCAG (Web Content Accessibility Guidelines) are W3C guidelines for ensuring web content accessibility for people with disabilities. Level AA is the mandatory standard for EU government websites under the accessibility directive.
What it is
What principles is WCAG built on?
In brief: WCAG is built on four principles: Perceivable (content accessible through different senses), Operable (keyboard navigation without mouse), Understandable (readable text, predictable behavior) and Robust (compatible with assistive technologies). Level AA includes 50+ success criteria.
Our approach
Why does it matter and how do we work?
Why it matters
Why it matters.
- 15% of the world population has some form of disability
- Mandatory for EU government websites (Directive 2016/2102)
- Google uses semantics and alt texts for ranking
- Reduces legal risks in some countries
- Improves UX for all users, including mobile
How we apply it
How we implement WCAG 2.2 AA.
- Semantic HTML markup with correct heading hierarchy (H1–H6)
- Text contrast minimum 4.5:1 (AA) and 7:1 (AAA) where possible
- Alt texts for all meaningful images
- Full keyboard navigation and focus state support
- ARIA attributes for interactive components
- Subtitles and transcripts for video and audio content
- Testing with screen readers (NVDA, VoiceOver)
Business value
What does it give your business?
An accessible website reaches a wider audience and is better indexed by search engines. Semantic markup and alt texts directly affect Google rankings. In Spain and the EU, WCAG compliance reduces legal risks and opens access to public tenders.

What do these standards mean?
- GDPR
- The EU regulation on personal data protection, in force since May 2018 and applying to every site with an EU audience.
- ISO 27001
- The international standard for information security management: how to protect code, data and access at every stage.

“The thing I see most often is a thought smeared across the page. The answer is there, but it assembles from four paragraphs spread top to bottom. A human will read on and put it together. A model takes the first third and leaves.”
